         7 . A battery comprising:
 a case having an accommodation space in the case; and   an electrode body disposed in the accommodation space in the case, and including positive and negative plates, each of the positive and negative plates having an active material layer including an active material and a substrate, and separator, wherein   each of the positive and negative plates has an active material layer forming portion in which the active material layer is formed on the substrate and a non-active material layer forming portion in which the active material layer is not formed, and   the non-active material layer forming portions of the positive and negative plates directly and perpendicularly contact an inner wall of the case.   
     
     
         8 . The battery according to  claim 7 , wherein
 the electrode body has a pair of the non-active material layer forming portions on both ends of the electrode body, and   the active material layer forming portion is provided between the pair of the non-active material layer forming portions.   
     
     
         9 . The battery according to  claim 7 , wherein
 the plurality of electrode plates is configured by a positive plate and a negative plate,   the separator is disposed between the positive plate and the negative plate, and   both of the positive plate and the negative plate include the active material layer forming portion and the non-active material layer forming portion.   
     
     
         10 . The battery according to  claim 7 , wherein
 the substrate is a porous body.
